Abstract:
The common analitical  expression for the phase  function of the diffractive optical element (DOE) to focus into a line in  noparaxial case is received. The phase function is given in the special  curvilinear coordinates. To calculate the function, that defines the energy  distribution along the line, the iteration method is proposed. The calculation  of the phase functions of the DOE to focus into the line-segment is produced.
Key words:
focuser, phase function,  curvilinear coordinates, iteration method, intensity, light field, ray tracing.
